Your bow appears to keep its width for around half of the working limb.
So the inner half will have some thickness taper, then where it starts to reduce in width the thickness taper should more or less stop and be a constant thickness out to the tips.
Tiller therefore should be not much bend out of the fade, this should increase slightly along to mid limb then the bend should be constant out to the tips.
That's quite tricky to read when you have a r/d side profile
As for the frets - if BL is badly tillered it will fret during tillering for sure however if you are close then it can be 'fretless' for many, many shots then one day they will show up. Don't ask how I know this......
Black locust is my favourite wood for this very reason - nowhere to hide with it unlike osage or other compression strong woods. As is say in TBB's black locust is the 'teacher wood'.
